Did you know that some areas of Cuenca y Guadalajara have a lower population density than Siberia?

ENTIENDO QUE LO HAS PUESTO DE EJEMPLO.
Igual que en almagro: - GeoestadÃstica y semivariograma. - Spatial PCA
Spatial dependence is checked with Moran’s I:
\[ I= \frac{N}{\sum _{i}\sum _{j} w_{ij}} \frac {\sum _{i}\sum _{j} w_{ij} (X_i - \bar{X}) (X_j - \bar{X})} {\sum _{i} (X_i - \bar{X})^2} \]
Range of spatial dependence is extracted from the semivariogram, the heart of Geostatistics, which is a tool that catch the spatial dependence according to the distance (see Figure 2): The semivariogram is the heart of Geostatistics
